201x7 Strong Base Anion Exchange Resin

201x7 is a Gel Type Strong Base Anion Exchange Resin based on polystyrene matrix with quaternary ammonium functional group. 201x7 gives high throughput and consistent quality. 201x7 resins in combination with 001x7 resins, gives excellent performance in mixed beds.

201x7 is high capacity resin which achieves lowest possible silica under varied water conditions. The resin is supplied in transparent moist bead form with high beads strength. The resin is suitable for demineralization system incorporating co-current and counter-current operations.

APPLICATIONS: 201x7 is recommended in the two bed system of demineralization system. The resin has a lower silica and carbonic acid leakages, hence gives higher silica removal capacity in demineralization units.
201x7 is also used as a mixed bed resin along with 001x7 as a polishing unit to achieve lowest residual silica in treated water and water of high purity is obtained. The resin is also used in absorption process, fractionalization process of weak acid, biochemical’s and pharmaceutical intermediates.
